Transferring files from my iMac to a Nokia 6288

Here's the deal: I bought a Nokia 6288 on Tuesday. I got a bit upset when I found out that iSync doesn't work with it out of the box. That was easy to remedy though, 'cause the 6288 is just a 6280 with firmware that works. What bugs me now is that the phone won't let me transfer files over USB without using PC Suite, which is Win only, or I have to use Bluetooth (which is dead slow when transferring 300+ MB). Anyone know a solution to this one? (preferrably free)
